Public bug reported:

I am not sure if it's a bug, however this works on the text console
without problem since years.

Yes, that is ugly, I know: sometimes I need to test (while developing)
softwares run as a specific unix user. To make this simple I often used
the trick to add a line to /etc/passwd with different user name but the
same numeric uid/gid as my account used to log in at lightdm's prompt.
Usually I remove that line then, but I forgot it, and after reboot I
couldn't log in.

According to /var/log/lightdm/lightdm.log lightdm treated as I want to
use as this "phantom" user, which is not true. Using simple console
login there is no such a problem.

AFAIK it's not so nice/legal to use /etc/passed entries refeering for
the same unix numerical uid, so I am not sure if it's a bug which should
be fixed, or it's something I shouldn't do, but as I've written above,
it works (and always worked since 1995 on Debian/Ubuntu/Slackware/RedHat
systems - as far as I can recall) on console logins at least.

By the way, I haven't added /etc/shadow entry for the user, only
/etc/passwd. And of course I tried to log in with my "normal" user, not
the "phantom".

thanks!
